Water Strainer

Pipeline Y-strainers (wye strainers) offer a compact and economical means of straining debris from pipelines. Keckley Y-strainers are furnished standard with drain connections and pipe plugs. Most commonly, Y-strainers are fitted in the field with nipples and drain valves to permit the strainer screen to be cleaned while the system is still in process. By opening the drain valve while the system is under pressure, the debris trapped in the screen is "blown" through this connection helping to reduce system shut-downs for maintenance and cleaning.

Wyestrainer purpose

Most pneumatic circuits are plumbed with the incoming air supply on the left side. However, there are situations where it's more practical to plumb in the opposite direction. This situation may be due to the location of existing air supply lines, space constraints, or other factors. The regulator is rotated 180 degrees in those cases, with its inlet port on the right side. Then, the gauge must be moved to the opposite face of the regulator to be viewed from the front. A right-to-left regulator is factory-configured for such applications.

Keckley Y-strainers are offered in both domestic and foreign castings with a wide variety of straining options for almost any application. Keckley does offer Y-strainers that meet the "American Recovery and Reinvestment Act" (A.R.R.A.) and "Buy American Act." Keckley also provides Y-strainers that meet or exceed military specifications: WW-S-2739: TYPE 1, WW-S-2739: TYPE 2, and NAVSHIPS 810-841499.

It's important to note the above features are not mutually exclusive. You can combine these airflow features for specific or niche applications. For example, some regulators have a combination of two of the features above. And it’s possible to have a regulator with all three functions!

Keckley offers bronze plumbing Y-strainers that meet the California and Vermont "Low Lead" legislation. Keckley Cast Iron, Ductile Iron, Nickel Aluminum Bronze, Carbon Steel, and Stainless Steel strainers already meet the requirement of having less than one quarter of one percent of lead by weight.

Y-strainers are available in Cast Iron, Ductile Iron, Bronze, Nickel Aluminum Bronze, Carbon Steel(like the popular SB-7 Model), Stainless Steel, and a variety of specialty metals including Alloy 20, Hastelloy C276, Monel, Chrome-Moly, and Titanium to withstand thermal or mechanical shock and corrosion. Canadian Registration Numbers (CRN's) are also available in specific models.

Non-relieving regulators can be challenging to set up because if the regulator is inadvertently adjusted a few psi too high, excess pressure must be vented by an external path (i.e., disconnecting a downstream line), which can be tedious. For this reason, a relieving regulator should be the default choice for compressed air.

Air pressure regulators are a critical component that ensures pneumatic systems' safe and efficient operations. However, choosing the right type of regulator can be challenging, especially if you're unfamiliar with its numerous types and features. In this blog, we'll explore three specific flow features of air pressure regulators; relieving, right-to-left, and regulators with backflow functions. And although the descriptions sound similar, their operation and applications are very different. Demystifying these three air pressure regulators will help you configure the correct components for your application, so keep reading.

In some applications, downstream pressure may rise above the setpoint. This rise can occur due to an outside mechanical influence in the circuit or thermal expansion in a hot storage tank. In such cases, a relieving regulator can vent the excess pressure, maintaining the setpoint. The relief flow passes from the outlet port, back through the relief port, and into the atmosphere.

Regulators with backflow functions, also known as reverse flow regulators, are used in applications where pressure downstream of the regulator must be exhausted during regular machine operation or system shutdown. An integral bypass check valve permits air to flow backward through the regulator when inlet pressure is removed. This type of regulator can be installed between a cycling valve and an actuator, allowing the actuator to extend and retract with two different pressures.

Choosing the correct type of pneumatic regulator depends on your application requirements. Relieving regulators are the default choice for most air applications, while non-relieving regulators are ideal for gases you wouldn’t want to be vented into the atmosphere. Right-to-left regulators are helpful when a system is plumbed with the incoming air supply on the right side. Finally, regulators with Backflow Function are used in applications where downstream pressure must be exhausted during machine operation or system shutdown.  Air pressure regulators are crucial in maintaining safe and efficient operation in pneumatic systems. By understanding the different types of pneumatic regulators and their features, you can make informed decisions and choose a suitable regulator for your specific application needs.

Non-relieving regulators are similar to relieving regulators but cannot vent pressure. They are mainly used for gases other than air that may create hazards if vented into the surrounding atmosphere (even inert gases such as Nitrogen can cause asphyxia in an enclosed space). Or, they may be used inside gasketed enclosures, where pressurization would cause a rupture disk to burst.

Relieving regulators are the most common type of pneumatic regulator. They are designed to maintain pressure at a preset level and are adjustable through a knob or screw. The regulator's internal valve modulates in response to changes in flow demand, allowing more or less air to pass downstream, as required to maintain the set pressure.
